The area of a rectangle is $\"A%5Br%5D=L%2AW\"$
\n" ); document.write( " $\"x%28x%2B11%29=126\"$
\n" ); document.write( " $\"x%5E2%2B11x-126=0\"$
\n" ); document.write( " $\"%28x%2B18%29%28x-7%29=0\"$
\n" ); document.write( "Two solutions:
\n" ); document.write( " $\"x%2B18=0\"$
\n" ); document.write( " $\"x=-18\"$ This solution doesn't make sense for this problem since length must be positive.
\n" ); document.write( " $\"x-7=0\"$
\n" ); document.write( " $\"x=7\"$
\n" ); document.write( " $\"L=7\"$
\n" ); document.write( " $\"W=7%2B11=18\"$ \n" ); document.write( "

\n" );
